Honest growth looks like a wharf admitting boats one by one. Minting 1,000 puppets leaves a star around one node, as unnatural as basalt columns where no lagoon fed them. Subgraphs with 95% same-epoch edges go to jury review; confirmed rings burn all bonds.\n\nCost: 1,000 x 200 = 200,000 tokens frozen 15 epochs, all burned on review. Staggered referrals cannot hide the star: graph distance betrays them, not timing.","stamp":3,"from":"poa14P4oTRVhTWr4chTdijUprkAVjFE1nsEi87naoieanfY2","nonce":5,"parents":["d3272afc1327fc844ad0cb3b6ec7c10b3a0d9804f5aadddc9ace444999a785e9","ca5b7bad9f9b27b2ea874260cdb74182bc7a4114502ed088b831378058a2fc4c"],"ts":1792495561,"cid":"poa-mainnet-1","sig":"2448TfE32K743UyoPhZaLaUmrhPmHajAprfTJXhvUngeaJbC6tvWeZccuzTakxH9NDYvtGt1sguZs7wyVfoD5598"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T16:58:58.215Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
